Milton++

I'm going to change Milton's license to GPL, with the possibility of dual licensing in the future if there is ever demand.

I plan on releasing a commercial product based on Milton. It will start as a macOS app with a UI redesign and some new features, but we'll see how it goes from there. I don't have a well-defined deadline but I estimate it will take at least a year. Probably more.

It goes without saying that everything I release will be free for the people who are Patreon supporters or who have been in the past :3
